Hi all, I'm new to CSS. I have recently created a site. I installed the template and created my own header image. When I view the site in Firefox with a resolution of 1024x768 it looks good, however when I view the site from another computer using either IE or Firefox with a higher resolution of 1024x768 the image repeats itself. Any ideas on how to correct this...? Thanks.

I've included a link to the site:

Also here is the container for the header:

Code:
/* Header */

#header-overlay {
	
	height: 109px;
	/*position: relative; */
	repeat:no-repeat;

	
}
